That’s a different Liberty Theater, Charmaine. Yours was located in the beighborhood of East Liberty. This site is for the Liberty still operating in Downtown Pittsburgh, a site formerly known as the Art Cinema.

Read about the original Liberty Theatre on Liberty Avenue in Downtown Pittsburgh (and see a drawing of what it once looked like)in my soon-to-be-published book WHERE THE MOVIES PLAYED IN DOWNTOWN PITTSBURG(H) from RoseDog Books. The Liberty Theatre opened in 1913 and is today known as the Baum Building. After a short time as the Liberty, it became Harry Williams' Academy Burlesque and was converted to an office building in the late 1920’s. Over the years the basement played host to Lenny Litman’s Copa, Staircase Lounge and for decades, the famous dance club known as Pegasus. James Kastner-Murrysville, PA

This is a 1919 photo. The theater is the same as the one in the preceding post. The address is given as Penn and Frankstown Avenues in East Liberty, so I am wondering if this is same geographic area as Liberty Avenue:http://tinyurl.com/p7naq
